Maximum Performance
Disk Drive Analysis package from Guzik Technical Enterprises delivers fast disk drive measurements on digital oscilloscopes. The package includes the Guzik Hardware Accelerator card and Guzik software environment installed on the Tektronix oscilloscope.
The 4 GHz analog bandwidth combined with 20 GSamples/sec sampling rate of Tektronix TDS7404 oscilloscope makes possible to perform PRML channel analysis up to 8Gbit/sec.
The unique design and strategic location of Guzik Hardware Accelerator card gives possibility to perform most time-critical measurements by hardware and in real-time with the speed of the oscilloscope acquisition.
Highly optimized Guzik graphical engine is capable to display large amounts of graphical data without slowing down the system.

Versatility
The Disk Drive Analysis package delivers wide range of disk drive oriented measurements including Parametric, NLTS, SNR and Pulse Profile. It integrates a highly flexible Digital PRML Channel with PR4, EPR4, E2PR4, and variable target PRML modes. The heart of the PRML channel is the digital clock and gain recovery with programmable bandwidth and customizable Viterbi decoder. The PRML channel also includes a wide range of programmable digital filters like low-pass and high-pass IIR filters and 32-tap FIR equalizer.
Disk Drive Analysis application provides semi-automatic optimization of Digital PRML Channel, auto-setup of product parameters, disk drive specific oscilloscope triggers and measurement gating.
